Create Kernel App

kernel create

Create a new Kernel application from a template. The CLI provides an interactive prompt to guide you through selecting a language and template, or you can specify all options via flags.

Flag	Description
--name <name>, -n	Name of the application directory to create.
--language <language>, -l	Programming language: typescript (ts) or python (py).
--template <template>, -t	Template to scaffold (see available templates below).

If any option is omitted, the CLI will prompt you interactively.

Examples

# Interactive mode (prompts for all options)
kernel create

# Create a TypeScript app with the sample template
kernel create --name my-app --language typescript --template sample-app

# Create a Python app with Browser Use
kernel create --name my-scraper --language python --template browser-use

# Create a TypeScript app with Stagehand (shorthand language flag)
kernel create --name my-agent --language ts --template stagehand

# Create a Python Computer Use app
kernel create --name my-cu-app --language py --template anthropic-computer-use

Next steps

After creating your app:

1. Navigate to the project directory:

   cd my-app
   

2. Install dependencies:

   • TypeScript: npm install
   • Python: uv venv && source .venv/bin/activate && uv sync

3. Authenticate with Kernel:

   kernel login or export KERNEL_API_KEY=<YOUR_API_KEY>
   

4. Deploy your app:

   # TypeScript
   kernel deploy index.ts
   
   # Python
   kernel deploy main.py
   

5. Invoke your app:

   kernel invoke my-app action-name --payload '{"key": "value"}'
   

Some templates require environment variables (e.g., OPENAI_API_KEY, ANTHROPIC_API_KEY). Set them using --env or --env-file flags when deploying. See kernel deploy for details.
